After the company became a joint venture in 1985, "Sanyangsheng" was owned by the state. Due to various reasons, the operating characteristics of "Sanyangsheng" disappeared for a time. In 1978, after Yuan Lunben, the former store manager, national commercial labor model, and Shanghai labor model, took office, he renovated the store on the original basis. The store's seal script "Sanyang Sheng" in golden characters shone brightly; palace lanterns were hung high in the store , carved beams and painted pillars; crystal clear marble counters and wooden shelves inlaid with flowers and jade, making the store more simple, elegant and unique. Many scenes in the movie "Morning in Shanghai" and the TV series "The Death of Buttercup" were shot here. At the same time, it has gradually restored its traditional business characteristics, and launched special packaging such as red pairs and square packages. It also improved bonsai production based on customer needs and produced sets such as "Dragon and Phoenix Show Prosperity" and "Fu Lu Shou Xi". Dried fruit bonsai has become a good gift for people to celebrate their birthdays or move into a house. In May 1985, at the Mingjian Crafts Exhibition held in the Netherlands, "Sanyangsheng" carefully produced the "Fu Lu Shou" three-star bonsai with unique shapes, which won praise and love from the audience.
